Seems OK for me.
Thanks, poty.
Now, just something which you - and others - may wish to try ...
I haven't listened to it yet but I did connect up the mains and switch it on - without letting the magic smoke out!

When I connect up a mains trannie, I always make sure the primary is oriented the right way round*. Jim's instructions (at least, for a 240v mains supply) to connect the 'Blu' wire to the Active tag on the PCB and the 'Wht' wire to the Neutral tag ... do not, in fact, deliver the 'correct way' - you need to reverse these.
* Google the BoundforSound article (repeated on other websites) about correct mains orientation of transformers - AIUI, it comes about as a result of parasitic capacitance of the transformer's primary (whatever the hell
that is!

). Using Jim's orientation, I measured around AC 140v between mains earth and the chassis; reversed, the DVM read < AC 2v. (NB: I am assuming all 370BX trannies are manufactured identically - which I suggest is a reasonable assumption.)
The BoundforSound article - and BTW, Clark Johnsen (the guru of absolute polarity) - claim that the
lower voltage reading between chassis and mains earth delivers the better sound.
NB: the mains cord needs to have a 'cheater plug' on its end, so the IEC earth tag on the component - and the chassis - is 'floating'. You get the 'mains earth' reference by sticking one of the DVM's probes into the earth hole in a wall socket.
